BACKGROUND: Currently, the risk of abdominal aortic aneurysm (AAA) rupture is determined using the maximal diameter (Dmax) of the aorta. We sought in this study to identify a set of CT-based geometric parameters that would better predict the risk of rupture than Dmax. METHODS: We obtained CT Scans from 180 patients (90 ruptured AAA, 90 elective AAA repair) and then used automated software to calculate 1-dimensional, 2-dimensional, and 3-dimensional geometric parameters for each AAA...

PURPOSE: Standard therapy in acute peripheral arterial occlusion consists of intra-arterial catheter guided thrombolysis. As microbubbles may be used as a carrier for fibrinolytic agents and targeted to adhere to the thrombus, we can theoretically deliver the thrombolytic medication locally following simple intravenous injection. In this intervention-controlled feasibility study, we compared intravenously administered targeted microbubbles incorporating Urokinase and locally applied ultrasound, with intravenous Urokinase and ultrasound alone...

INTRODUCTION: Prophylactic open surgery is the standard practice in patients with connective tissue and thoraco-abdominal (TAAA) and aortic arch disease. Branched and fenestrated devices offer a less invasive alternative but there are concerns regarding the durability of the repair and the effect of the stent graft on the fragile aortic wall. The aim of this study was to evaluate mid-term outcomes of fenestrated and/or branched endografting in patients with connective tissue disease. METHODS: All patients with connective tissue disease that underwent TAAA or arch aneurysm repair using a fenestrated and/or branched endograft in a single high volume centre between 2004 and 2015 were included...

OBJECTIVE: Vascular closure devices have been used to achieve hemostasis of percutaneous access sites following endovascular procedures, with reported decreased time for arterial control as well as decreased time to ambulation. We sought to determine rates and risk factors of postoperative bleeding complications and failures using these devices from a single institution experienced in the use of vascular closure devices. METHODS: All patients undergoing arterial endovascular procedures with percutaneous access between March 2010 and October 2015 at a single institution were identified and analyzed (n=894)...

INTRODUCTION: Deep wound infections in the groin region can result in an acute or life threatening condition. Especially when there is no suitable vein available because of many reasons (e.g. previous surgery, small vessel diameter). Synthetic prosthesis sometimes are not 'first-choice-technique' because of contamination or infection. It was ad hoc hypothesized in an acute setting that a segment of an occluded Superficial Femoral Artery (SFA) could be used as a conduit in combination with eversion technique, known from carotid surgery...

Pancreaticoduodenal artery aneurysms (PDAA) are rare, but rupture can occur at any time regardless of the size. We describe here the case of 53-year-old woman who presented wit a ruptured PDAA associated with compression of the celiac trunk by the median arcuate ligament. We first performed revascularization of the celiac trunk without intervening on the PDAA, because of surgically hostile conditions. We observed complete regression of the PDAA, probably due to the dramatic decrease in inflow to the PDAA, thanks to the revascularization procedure...

Type II Abernethy malformations, characterized by side-to-side portosystemic shunting with preserved intrahepatic portal venous system, have been treated with shunt closure surgically and endovascularly. Three-dimensional printing has been used to develop highly accurate patient-specific representations for surgical and endovascular planning and intervention. This innovation describes three-dimensional printing to successfully close a flush-oriented type II Abernethy malformation, with discrepant dimensions on computed tomography, conventional venography, and intravascular ultrasound, using a 12-mm AMPLATZER atrial septal occluder device...

INTRODUCTION: Aorto-esophageal (AEF) and aortobronchial fistula (ABF) after TEVAR are rare complications with catastrophic consequences without treatment. In this case report we presented a patient with AEF and ABF after TEVAR successfully treated with endograft explantation and replaced by Dacron graft followed by esophagectomy and left principal bronchus repairing. CASE REPORT: We report a patient with AEF and ABF after TEVAR who was evaluated due to dysphagia and chest pain followed by hematemesis and hemoptysis...

BACKGROUND: Superficial vein thrombosis is a common venous condition. Recent studies have shown that SVT is associated with high frequency of thromboembolic complications: from 22 to 37 % for deep venous thrombosis and up to 33% for pulmonary embolism. OBJECTIVES: To assess the prevalence of major hereditary and acquired thrombophilic factors in patients with SVT. PATIENTS AND METHODS: 66 patients presenting with primary ST underwent evaluation for thrombophilia: molecular testing for the factor V Leiden and factor II G20210A (prothrombin) mutations, protein C, protein S, antithrombin deficiency, presence of lupus anticoagulant, as well as anti-cardiolipin antibody titers...

INTRODUCTION: Current recommendations suggest lifetime followup for EVAR patients to avoid consequences associated with endoleak and aneurysm enlargement. Followup compliance has been reported between 43-92%, with most single-center studies citing successful followup surveillance at less than 60%. We investigated followup completeness with a defined surveillance program and subsequent secondary intervention prevalence from a single center. METHODS: Our surveillance program notified patients of the need for followup imaging and surgeon review...

The objective was to compare immediate and long-term results of systemic thrombolytic therapy (STT) and catheter-directed fragmentation (CDF) with local thrombolytic therapy (LTT) in patients with massive pulmonary embolism (PE). METHODS: 209 patients with massive PE (the high risk of early death) were included in our study. From 2008 till 2010 in the first group (n=102) STT was performed. From 2011 till 2013 in the second group (n=107) CDF with LTT was carried out. Echocardiography and pulmonary arteriography were performed in all patients on admission to hospital and in 5 days after treatment...

INTRODUCTION AND OBJECTIVES: Since 2009 the Society for Vascular Surgery has advocated annual surveillance imaging with ultrasound (US) after the first post-operative year for uncomplicated endovascular aneurysm repairs (EVAR). We sought to describe diffusion of US into long-term routine surveillance and to estimate potential cost savings among Medicare beneficiaries after EVAR. METHODS: Using Medicare claims data we identified patients receiving EVAR from 2002 to 2010 and included only those who did not subsequently have re-interventions, late aneurysm-related complications or death...

Segmental arterial mediolysis (SAM) is a non-atherosclerotic, non-hereditary vasculopathy that most commonly involves abdominal aortic branches and predominantly affects middle-age and elderly populations. Lysis of the outer arterial media results in separation of the media from the adventitia leading to dissecting aneurysms and/or pseudoaneurysms. We report a unique case of a 47-year-old man who presented with bilateral internal carotid artery dissection followed by dissections and aneurysms involving multiple visceral arteries...
